Last year’s event raised $25,000 to support 826 Seattle’s free programs for students ages 6-18. Organizers hope to raise at least $28,000 this year.

You can register to form or join a dance team, and be ready to dance for five straight hours. You must raise at least $150 in donations (which makes you eligible for prizes). Fun costumes encouraged.

Doors open at 5:30 p.m. on June 21, dancing begins at 6 p.m. The Grand Prize will be awarded after 11 p.m. Joe & Nancy Guppy of Seattle Channel’s “ArtZone” are hosting, and DJ El Toro of KEXP will spin tunes.

Speaking of 826 Seattle fundraisers, the organization raised more than $170,000 at its May 4 “People Eating & Giving” event, where authors Sherman Alexie and Jess Walter talked with John Roderick of The Long Winters about their support for 826.
